To allwhom.it-may concem: v V M Be itknow'n that I, GEORGE M.]KURNALIA of .Rensselaer, and State of New York,'have blanks in the manufacture of collars, etc.

invented certain new'and useful Improve-' ments in Folding-Machines, of which the following is a specification.

- Reference may bejhad tothe'accompanying drawings, and the reference characters marked thereon, whichrform apart of this specification; Similarv characters refer to s milar parts 1n the several figures therein. Thls inventlon relates to foldmg-machmes of various kinds. such for example as ma-.

chines for inturningthe edges of textile The principal object of the invention is to inform the operator of the machine of the number .of blanks turned or the number of operations of the machine.

Other ob ects will appear in connection with the followingdescription. V

Figure 1 of the drawings is a view in front 1 elevationof the upper portion ofthe foldin machine with a portion broken away an shown in sectio n Fig- 2 is a viewinelevation of the right hand end ofthe machine shown in Fig. 1.

Fig. 3 is a view infront elevation of the counting-device detached. I

Fig. 4 1s a view in rear elevat on of the same.

. 1 Fig. 5 is a top plan view ofthe same with vice, and the parts mounted I thereon, the

the'casing partly broken away, and shown insection. f i' h Fig. 6 is a view 'showing-the interiorof the body of the casing of thecounting-derear cover being removed. I

Fig. 7 is a similar view of the detached rear cover of the casing of. the countingdevice with. the parts'mounted thereon.

Fig. 8 is a view in rearelevation of .the

' counting-device completedetached from the A die, 3, ismounted-upon adie-head, 4,

carried by an oscillatory arm, 5, pivoted at 6, upon a bracket, 7, in fiire'd'relation to the "frame of the machine, wherebyjthe die-head, 4', and die, 3, are adapted to be swung toward and from the bed, 2, the die, 3, resting upon the blank'on the bed during the folding operation.

The arm, 5, may be actuated by. means of a link, 8, connected with any suitable source of power in the usual manner. V

' Infolders, 9, are movableinwardly and outwardly over the bed, 2, and serve to inturn the edges'of the successive blanks over the edges of the die, 3. The infolders may be moved inwardly or outwardly .in any known manner. v V I The parts thus far described are commonly used in folding machines and their construction and manner ofoperation will be readily understood so that further de- Q iption of these parts, as well as the generaloperation and construction of the machine, will be. unnecessary.

In carrying out my invention in it's/preferred form, I'mount upon the die-head, 4,

by means of a screw-attached clip, 10, a

counting-device of which 11 isthe body of the casing for the device, and 12 is the rear cover for same, secured to the body, 11, by screws, 13. 4 V

The casing also .has a front cover, 14, screwedto the body by means of screws, 15. Upon the frontcover is mounted a dial, 16, numbered from 1 to 24, adapted to be read. in connection ithTan index, 17 operated by a. ratchet-wheel, 18, mounted. within the body of the casing. V

I Thev ratchet-wheel, 18, is engaged by a pawl, 19, carried by a rod, 20, adapted'to reciprocate longitudinallyin slideways, 21,

mountedon the inner side of the front cover, 14, of the casing. 1 j

A coil-spring, 22, tends to resist upward movement of the rod, 20.

The: rod, 20,. extends downwardly out throughjan opening, at 23, in the bottom of yond. the bottom surface of the die, 3, shownin Fig. 2. The parts are so arrested that each up- 2 Ward movement of the rod, 20, will through the mediumoflthe pawl-and-ratchet mechathe casing-body to a point substantially be-' nism impart to the index, 17, a rotative movement from one dialmember to the next successive dial member. 7

.The rod, 20, thus projects downwardly from the cheat apoint W'ithinthegeneral contour of'the die, ivhereby it is adapted to engage a blank resting on'thebed during the foldingoperation. r f V V The portion of he'bed covered by the blank during the folding operation is provided with an opening, 24,, Opposite the point Where the rod, 20, engagesthe bed supported blank into which opening,2 1, the

end of the rod, 20,'idly passes when no blank "be, arrested by its-engagement With the blank causing .a. relative upward movement of the rod, 20,- with respect to the ratchet-Wheel,- 18, thereby causing the pawl, 19, to operate- 7 the index, 17.

.Operations of the machine for purposes of experiment or adjustment Without the use of blanks Will not thus be registered by the counting-device, and only, the actual turning of the blanks illbe registered.

.Should it be desired'to operate the1na .ehine at times upon blanks Without regis tering the operations .on the counting-de- VlCG, the. rod, 20, may be secured in raised position as-indicated by dotted llnes, 25, 1n

'Fig. 8, by means .of a set-screw, 26, which maybe screwed'into tight engagement With the upper end of the rod, 20,'Which projects from the top ofthe casing. f

As the principal object of the invention is to make it unnecessary vforthe operator to count the blanks after they have been folded and to avoid mistakes in counting, I preferably provide .the countingsdevice With a signal bell, '27, or ,otlieinaudible signal which is automaticallyxsounded upon the folding of. the last of a number of blanks. V The counting-device may be designed for sounding such a signal upon the folding of the last of any predetermined number of -blanks. i

" As illustrated I have shown a cam, 28,

fixed upon the ratchet-Wheel, 18, adapted at p redetcrmined each- 24th step-by-stepmovement of the in deX, 17, to release a trip, 29, carrying a hammer, 30, Wh10ll Whenereleased rings the bell, 2?,the bell being mounted uponothe.

7 outer. side-- of the rear casing-cover, l2, and

and the counting-device will Y by Letters Patent isthetrip, 29, being pivotally inountediat 31,

upon the inner side of said cover.

A co1l-spr1ng, 32, serves tov actuate the hammer, 30,,whenrthe trip is released from engagement with the cam, 28. V l The operator thus need pay no attention to the number indicated by the index, 17,

as he Willbe informed by the ringing ofthe bell that twenty-four blanks have been folded the machine, or

For certain purposes of thei'nvention any known form of counting-device maybe em operatethe counting-device when its moveployed which has an operatingmember idly movable nto the opening 111 the bedwhen .no blank 1s ,jpresent, and livhlch 1s caused to ment into said opening is prevented by 'a 7 blank covering the opening.

lVhile'Ihave described my invention in its preferred application to folding machines, it will be apparent that the invention may 'beoapplied to anymachine open ating upon blanks of various kinds, such as collar blanks, cards and the like wherein the blank to be operated upon by the machine covers the opening in the bed, and causes the counting-dev ce to be ,operatedby preventing an operating member of the counting-device from enteringksaid opening,

What I claimaslnew and desire to secure 1. In a folding machine, the; combination w th a bed provided w th an open ng in a blank-covered portion .of. the bed; :a diehead movabletoivard and from the bed;a'

counting device mounted upon the die-head and. movable therewith toward and from the bed, said counting-device having. an operating vmember adapted to :idly enter (1 opening in the bed ;in the .absencebf a'blank on the bed, and caused to-actuatethe count ing-device when the movement of said memberlis ,arrested by engagement With-a blank member into saidopening. V

on the zbe'qreventingjthe entrance offsaid 2.7 In a foldingmachine, the combination with a bed provided with an openingfin a blank-covered portion. of the bed; and a thehead movable toward and fromutheubed'; of a conntingedevice actuated by pawl-and 1 ratchet mechanism, having-a pawl-carrying rod whichenters said opening (in the" bed j when no blank is present .on the bed, and
